I just installed Debian 9.2.1 on an old laptop as a cheap server. The computer is not physically accessed by anyone other than myself, so I would like to automatically login upon startup so that if I have to use the laptop itself rather than SSH, I don't have to bother logging in. I have no graphical environments installed, so none of those methods would work, and I've tried multiple solutions such as -root-login-in-debian-8-0-console-onlyHowever all it did was result in no login prompt being given at all... So I reinstalled Debian.What can I do to automatically log in without a graphical environment? Thanks!
How to Automatically Login to Linux
I just want to add to this discussion that the accepted answer pertains to virtual terminals. In my case, I had to edit a separate service file which is used for serial terminals. The file is found at /lib/systemd/system/serial-getty@.service and the same procedure of adding --autologin to the appropriate line does the trick.
First if you wish to only have one TTY that is running the program, and not be able to log in to any other tty, THEN edit your /etc/systemd/logind.conf, and change #NAutoVTs=6 to NAutoVTs=1. Doing this will keep you from logging in on the terminal!
Now keep in mind this will run without a bashrc. This means if you use something like screen then you won't get all your usual aliases/etc. To fix that, use the standard auto-login above, but add this to your .bashrc:
Step 5: Next to the autologin-user line, write in your username. Be sure to write it exactly as it appears on the system. One missed character could mess up your entire LightDM configuration.
The option Type=idle found in the default getty@.service will delay the service startup until all jobs are completed in order to avoid polluting the login prompt with boot-up messages. When starting X automatically, it may be useful to start getty@tty1.service immediately by adding Type=simple into the file.
It's certainly annoying when you leave your Mint desktop idle for a couple of minutes only to be welcomed by a login screen asking you to enter your password again. What if you're the only one using the computer and don't want to type your lengthy and secure password every time you want to log in?
At the time of installation, Linux Mint prompts you with the choice of logging in automatically or having to type in the password to sign in to your desktop. But if, for some reason, you selected the wrong option, or have decided to change your mind and want to enable automatic login on your Mint desktop, here's how to do it.
There's an additional configuration that commands the display manager to wait for a specified amount of time before triggering auto-login. If you want to add a delay, enter the time in seconds in the field next to the Delay before connection (in seconds) label.
Password-based login proves to be essential if multiple people share a computer. It adds an extra layer of security to your desktop and helps you keep your private files and settings secure. Therefore, if you've auto-login set up and want to remove this setting, follow the steps below:
Configuration differs for virtual versus serial consoles. In most cases, you want to set up automatic login on a virtual console, (whose device name is ttyN, where N is a number). The configuration of automatic login for serial consoles will be slightly different. Device names of the serial consoles look like ttySN, where N is a number.
Getty can be used to login from a virtual console with a default user, typing the password but without needing to insert the username. For instance, to prompt the password for username on tty1:
Next, in the automatic login category, enter the username, and delay before connections time in seconds in the given field. If you want to check all the users, then open the Users and Groups application from the application menu, and it will show the list of all the users.
Check the username information and enter it in the given field. Then enter the delay before time in seconds. It refers to the time the system will take to automatically log in to the user at the end of the boot process.
Putting script in /etc/profile.d/ is working but for me it made many problems.I put a script (interactive script!) in that folder and when I login from ssh, the script is run with success.But when I reboot the machine, the machine can't boot. my script was interactive means expect to read the user answer for a question.so the boot stuck with no good error.On the second machine (newer PC), the boot stack since the syslog.1 file (/var/log/syslog.1) got to 90GB!!!It looks like the machine gave some answer to the script. the answer was invalid and the script asked for a valid answer and so on and the syslog got bigger and bigger till the machine couldn't boot.
I partially figured this out on my own from reading about getty in /etc/inittab, which led me to ExecStart on my system, and a quick google search led me to -can-i-autologin-to-desktop-with-systemd which gave me the auto-login syntax of /sbin/getty.
In situations where password is the only authentication method available, sshpass can be used to automatically enter the password. Please pay particular attention to the SECURITY CONSIDERATIONS section of the man page. In all three options, the password is visible or stored in plaintext at some point:
Gentoo supports different init systems. Each init system requires their own solution for auto-login.All involve passing --autologin to the terminal handler called agetty, but how this is done differs per init system
From my Mac Terminal I can login via ssh to my various Ubuntu servers without entering a password. That's fine. But the work I do in Ubuntu requires me to have root access, so immediately after login I always execute sudo suwhich is an extra step and requires manually entering my password at that point.
Suggestion: if you're doing this, at least disable password login for SSH, and use keys instead. Otherwise, as others have already observed, your system is a single password away from being wide open. With keys, at least the attacker needs to filch your identity key first.
HelloI was a Ubuntu user and it automatically logged me in to the desktop I don't want to enter my password every time I boot into the system Is it possible to do the same in arch? If so how?
Note in this screenshot I've got the ssh connection listed at the top, and when I click on it it opens ssh.exe and prompts me for a password. I have no ssh keys on my system that would enable auto-login, hence the password is needed.
I want to be able to type "ssh pi@hanselpi4" from my Windows machine and automatically be logged in. More specifically I want to click the profile and have it Just Work.I willMake a key on my Window machine. The FROM machine, in this case, Windows. Then I want to ssh FROM here TO the remote Linux machine. Tell the Linux machine (by transferring it over) about the public piece of my key and add it to a specific user's allowed_keys.
I'll run ssh-keygen to make a key from my command line on Windows. I just hit enter to generate it but you can make your own filename if you want, just use the full path and make sure you keep track of where things are. Defaults are usually best.
NOTE: I'm type'ing (cat on Linux is type on Windows) that text file out and piping it into SSH where I login that remote machine with the user pi and I then cat (on the Linux side now) and append >> that text to the .ssh/authorized_keys folder. The folder is implied but could be added if you like.
At this point I can click the menu item in Windows Terminal and automatically be ssh'ed/logged into the remote terminal. But, scandalously, the Terminal menu item has no icon. This is clearly unacceptable M$sft sucks, right? I'll go get a nice 32x32 Raspberry Pi Icon and put it somewhere. You might put yours in a Dropbox or OneDrive so they are available everywhere you go.
If the site is launched from the LastPass vault or from the LastPass browser extension, it will still automatically fill and log you into the site, even if your site Preferences are set with "Autologin" disabled and "Autofill" disabled.
Logging in, logging on or a login is the entering of identifier information into a system by a user in order to access that system (e.g., a computer or a website). It is an integral part, but only a part, of computer security procedures. A login generally requires the user to enter two pieces of information, first a user name and then a password. This information is entered into a login window on a GUI or on the command line in a console (i.e., all-text mode), depending on the system and situation.
There is, of course, a security risk to skipping the login, and it is not good training for future system administrators. However, the risk for single-user systems in relatively secure environments, such as a private home, is fairly low and could well be worth taking for the added convenience.
It should also be kept in mind that there are relatively simple ways for intruders to access computers even if logins are required. Also, there are other techniques that can be used to secure computers that have been set up to bypass manual logins.
To enable automatic login for a user, check the small box in the center of the General pane that says Automatic login. Just below that select the user name to which the automatic login applies.
This configuration window changes settings for the gdm daemon, which controls the graphical login screen for GNOME. A daemon is a program that is designed to run continuously in the background and be available when needed. Changes made to gdm will take effect immediately.
The Login Manager window appears to the right. Root permission, which is necessary in order to make changes, can be obtained by clicking on the Administrator Mode button at the bottom of the window and then entering the root password in the space provided. The next step is to select the Convenience tab near the top of the window, followed by checking the box that says Enable auto-login and selecting the name of the user for which the automatic login will occur. The procedure is completed by clicking the Apply button and closing the window. 2ff7e9595c
